IMPROVEMENT IN LlFTlNG-JACKS.

Specification forming part of Letters Patent No. 202,666, dated April23, 1878 application filed March 30, 1878.

To all whom it may concern:

Be it known that I, ORLANDO 1/. PRICE, of Mount Vernon, in the county ofKnox and State of Ohio, have invented a certain new and ImprovedLifting-Jack; and I do hereby declare that the following is a full,clear, and complete description thereof, reference being had to theaccompanying drawings, making a part of the same.

Figures 1 and 2 are side views of the lifting-jack, shown in difl'erentpositions. Figs. 3 and 4 are detached sections.

Like letters of reference refer to like parts in the several views.

The nature of this invention relates to a lifting-jack; and the specialnovelty of the same consists of a peculiarly shaped head pivoted to thelifting end of the jack-lever, which, when the jack is used for liftingthe axle of a vehicle, is placed under the hub of the wheel, so that onlifting the axle the wheel is drawn partially off, so that theapplication of the grease or oil to the axle can be made Withoutremoving the wheel or handling it.

A further and more full description of the invention is as follows: Thestandard of the jack consists of a tube, A, Fig. 1, supported on afoot-piece, B. In the tube is loosely fitted a shaft, 0, in the upperend of which is pivoted the lever D. To the short arm of the lever ispivoted a head, E, a detached view of which is shown in Fig. 3, whichrepresents the upper side or face of the head. In the side of thestandard is a slotted opening, a, communicating with the series of holesor rests c, for receiving the pin d projecting therein from the shaft 0.p

The practical operation of the jack will be readily understood onexamination of the drawing, Fig. 1, in which F represents a wheel or asection of one. Under the hub, on the outer side of the spokes, the headE of the jack is adjusted, so that the face of the head will lie againstthe spokes, as shown in said Fig. 1. On depressing the long arm of thelever, the wheel will be raised, and at the same time it will be drawnfrom the axle, as shown in Fig. 2. To the exposed part of the axle isapplied grease, and the wheel again slipped on by lowering the jack.

It will be obvious that by this means a Wheel can be greased withoutremoving it from the axle or applying the hands to the wheel for thatpurpose.

On lifting the wheel the arms G of the head prevent the hub fromslipping from the jack, while the lip H of the head holds the wheelsteady and upright while being lifted, and at the same time keeps thewheel from striking against the standard.

In order to use the jack for lifting a body directly upward, the head isadjustable, as shown in Fig. 4, face upward, in which position it isplaced under the object to be raised.

The jack may be adjusted as to height by shifting the pin d in the holesor rests.

I am aware that tubular standards for lifting-jacks have been used, andthat heads have been pivoted to the end of the lifting-lever; hence I donot claim, broadly, a lifting-jack consisting of such parts; but thatwhich distinguishes my invention from others is the peculiar shape ofthe head, whereby I am enabled to apply the jack to the front of thewheel, and, while lifting said wheel, draw it partially off the axle, sothat it can be greased without taking the wheel entirely on.

What I claim as my invention, and desire to secure by Letters Patent, is

In liftingjacks, a head, E, pivoted to the handle or lever D thereof,and provided with projections G, between which projections to receivethe hub of a wheel, and a depending lip, H, for bracing and steadyingsaid wheel by being held against the spokes in the application of thehead to the hub of a wheel, substantially as herein set forth, and forthe purpose specified.
